Tattoos are fashionable; even children get henna tattoos. However, medical studies indicate that they are not entirely harmless and health authorities warn of the risks.

Babies’ skin changes rapidly; during puberty skin becomes adult; and at maturity women’s skin ages faster than men’s one.
Skin colour is one of the main differentiating features between people of different ethnic origins.

Skin Scan is a new Apple App Store application that analyses moles and marks on the skin. A simple photo is analysed and compared with a previous photo using a custom-designed algorithm that calculates the fractal dimensions of the mole. The app alerts the user if they need to visit a dermatologist.
The creators of Skin Scan, including two dermatologists and two mathematicians, maintain that it is well worth spending ten minutes analysing your skin if it can save ten years of your life. Skin Scan was not designed, however, to replace regular medical check-ups.
